    That went badly

    Been working on my 1960 vintage Blue Streak to get it up and running. New pump cup & seal kit, all the usual suspects.

    Newbe dumb question

    Have a new (30 shots) Mrod F&T that leaked down from 3,000 to 2,500 PSI over 2 days. So far 3 hours into balloon test looks like the gage is the source. Do I need to depressurize before I tighten it? OFG

Returned to Airgun Depot for refund and ordered a Mrod F&T to replace the leaker. 30 shots took 900...
